Abstract

The present invention relates to a method for acquiring a channel characteristic, a user equipment (UE), and a base station. The method comprises: a UE acquiring quasi-co-location configuration information, wherein the quasi-co-location configuration information is used for indicating that at least one channel characteristic of a first antenna port and a second antenna port is quasi-co-location, and the first antenna port and the second antenna port respectively correspond to different carriers; the UE determining, according to the quasi-co-location configuration information, that at least one channel characteristic of the first antenna port and the second antenna port is quasi-co-location; and the UE obtaining, from signals received at the first antenna port or at the first antenna port and the second antenna port, the at least one channel characteristic, that is quasi-co-location, of the second antenna port and the first antenna port. A quasi-co-location configuration method for cross-carrier antenna ports is adopted to solve the problems that some cell of a certain carrier cannot determine a channel characteristic of an antenna port through quasi-co-location configuration due to lack of a certain reference signal, and the quasi-co-location configuration is inflexible; therefore, a cell and a carrier without a certain reference signal are enabled to use the quasi-co-location configuration to determine a channel characteristic of an antenna port, which expands a signal type corresponding to an antenna port used for quasi-co-location reference and a channel characteristic corresponding to quasi-co-location, also expands an application range of the quasi-co-location configuration, and makes the quasi-co-location configuration more flexible.

Description

Method for acquiring channel characteristics, user equipment, and base station

TECHNICAL FIELD The present invention relates to communication technologies, and in particular, to a method, a user equipment, and a base station for acquiring channel characteristics.

In the Long Term Evolution (LTE) system, the large-scale characteristics of the channel transmitting the signal on the other antenna port can be inferred by transmitting the channel of the signal on one antenna port, then the two antenna ports are called Total station (QCL, Quasi-Co-Location). Among them, the large-scale characteristics of the channel include: Delay Spread, Doppler Spread, Doppler Shift, Average Gain, and Average Delay. One or more of them. For example, the user equipment (User Equipment, UE) may determine a Demodulation Reference Signal (DM RS) antenna port and a CSI-RS configured by the same cell high-layer signaling according to the quasi-co-located configuration information sent by the base station. The antenna port is quasi-co-located. For example, the UE may further determine, according to the configuration information sent by the base station, that one CSI-RS antenna port configured by the high-level signaling and one CRS antenna port configured by the same cell high-level signaling are quasi-co-located. Since the antenna ports of the quasi-co-located stations configured by the base station are all on the same carrier, the UE can only obtain the channel large-scale characteristics of the DM RS or the CSI-RS according to the channel characteristics corresponding to the antenna ports on the same carrier. Therefore, for the case where there is no CRS or no CSI-RS in the cell on the carrier, the antenna port of the cell on the carrier cannot implement the quasi-co-site, and if the quasi-co-site can only be performed on the same carrier, it will also be The gain of the co-site is greatly limited.

The implicit notification can be: Notification by non-quasi-communication-related dedicated signaling. If the base station informs the UE of the reference carrier of the cell, the first antenna port for the quasi-co-located reference is the corresponding reference carrier unless the carrier information for indicating the first antenna port of the quasi-co-site reference is explicitly notified. Antenna port; or the base station notifies the UE of the reference cell of the cell, then the first antenna port used for the quasi-co-site reference is unless the carrier information for indicating the first antenna port of the quasi-co-site reference is explicitly notified Corresponding to the antenna port of the cell; or the base station notifies the reference cell on the reference carrier of the UE-cell, then the quasi-co-site is used unless the carrier information indicating the first antenna port of the quasi-co-site reference is explicitly notified First reference The antenna ports are all antenna ports corresponding to the reference cell on the carrier. In this embodiment, the quasi-co-located station configuration information may further include carrier information of the first antenna port. The carrier information may be at least one of the following: cell identification information or carrier identification information, where the cell identification information may be the serving cell index number information; the carrier identification information may be the carrier frequency index number information.

The quasi-co-location configuration information may be included in the configuration information of the signal corresponding to the second antenna port, where the configuration information corresponding to the second antenna port includes carrier information and/or correlation of the signal corresponding to the first antenna port. Index number, etc. For example, the first antenna port is an antenna port of a cell-specific reference signal (CRS), and the second antenna port is an antenna port of a CSI-RS, and the configuration information of the CSI-RS includes carrier information of the CRS, such as the CRS. Corresponding serving cell index number. Before the base station notifies the UE of the quasi-co-location configuration information, when the quasi-co-site information is configured, the UE may be configured in the first mode or the second mode: mode 1, the antenna port of the first signal of the first cell, and the second signal of the second cell. The antenna port is quasi-co-located with respect to at least one channel characteristic; for example, an antenna port of one CSI-RS of the first cell and a CRS or RCRS of the second cell (reduced CRS, a CRS that occupies a reduced number of REs) The antenna port is quasi-co-located with respect to at least one channel characteristic.

Thereby the antenna port of the first signal of the first cell and the antenna port of the second signal of the second cell are quasi-co-located with respect to at least one channel characteristic (such as channel characteristic A or B). For example, at least one of the antenna ports of one CSI-RS of the first cell and the antenna ports of the CRS or RCRS of the first 'area is quasi-co-located, and the antenna port and the CRS of the first cell and the RCRS The at least one channel characteristic in the antenna port of the CRS or RCRS of the two cell is quasi-co-located. Thus, the at least one channel characteristic of the antenna port of the CSI-RS of the first cell and the antenna port of the CRS or RCRS of the second cell is quasi-co-located. Further, the UE may receive the letter according to the CRS of the second cell or the antenna port of the RCRS. Obtaining the at least one channel characteristic of the antenna port of the CSI-RS of the first cell, or the UE may be based on the antenna port of the first 'j, the CRS or RCRS of the area, and the antenna port of the CRS or RCRS of the second cell The received signal obtains the at least one channel characteristic of an antenna port of the CSI-RS of the first cell. Optionally, the base station may further notify the UE of the deviation configuration information, so as to set a deviation value of at least one channel characteristic between the first antenna port and the second antenna port, and adjust according to the deviation value, At least one channel characteristic of one of the antenna ports and the second antenna port is quasi-co-located. Specifically, the deviation value may be a relative value, such as a time domain channel characteristic of the first antenna port and a time domain channel characteristic deviation value of the second antenna port. Here, the deviation value of the channel characteristic may be a deviation value of at least one of the time domain channel characteristics, the frequency domain channel characteristics, and the power domain channel characteristics. When the deviation value is 0, the deviation value does not need to be notified to the UE, or when the UE does not accept the deviation value, the UE assumes that the deviation value is 0. In this embodiment, the UE receives the deviation configuration information, and adjusts the channel characteristics in the antenna port of the cross-carrier according to the deviation value in the deviation configuration information, and then reaches the quasi-co-site, further realizing the cross-carrier antenna port. A total station, and make the quasi-co-location configuration more flexible. Another embodiment provided by the present invention is similar to the embodiment shown in FIG. 1 , except that in this embodiment, a part of the quasi-co-located station configuration information may be notified by the base station to the UE, and the part of the quasi-co-located station configuration information may be used by the UE. Predefined. The part of the quasi-co-located station configuration information may be notified by the base station to include, explicitly notified by the base station, and/or implicitly notified by the base station. In this embodiment, a part of the quasi-co-located station configuration information is notified by the base station to the UE, and the part of the quasi-co-located station configuration information is predefined by the UE, so that the manner in which the UE obtains the quasi-co-site configuration information is more flexible. Another embodiment provided by the present invention is similar to the embodiment shown in FIG. 1 , except that in this embodiment, the quasi-co-located station configuration information acquired by the UE is used to indicate that the first antenna port and the second antenna port are related to The average gain is a quasi-co-site, and the method shown in the second embodiment and the third embodiment can also be used in the manner of obtaining the quasi-co-location configuration information. In this embodiment, the method for acquiring channel characteristics further includes:: receiving, by the UE, an RSRP value. The The RSRP value is obtained after measurement processing on at least one of the first antenna port and the second antenna port. Specifically, the UE may measure an RSRP value according to the first antenna port, and measure an RSRP value according to the second antenna port, and the UE reports the RSRP value measured on the first antenna port or the RSRP value measured on the second antenna port, or A statistical average or weighted average of the two RSRP values is used to obtain a final RSRP value, and the resulting final RSRP value is reported. Alternatively, the UE may jointly measure an RSRP value according to the first antenna port and the second antenna port, and report the RSRP value obtained by the joint measurement. Or, in this embodiment, the UE obtains the deviation configuration information in addition to the quasi-co-location configuration information, where the deviation configuration information is used to indicate that: the first antenna port and the second antenna port are adjusted according to the deviation value, and the average gain is It is a quasi-common station. The rest of the method is similar to the embodiment shown in FIG. 1. The manner of obtaining the quasi-co-location configuration information can also be performed by using the method shown in the foregoing embodiment, and the method for obtaining the deviation configuration information can also use the method shown in the foregoing embodiment. When the deviation configuration information is used to indicate that: when the first antenna port and the second antenna port are adjusted according to the power offset value, and the average gain is a quasi-common station, after the UE receives the deviation configuration information, the method for acquiring the channel characteristics further includes: The UE reports an RSRP value. The RSRP value is measured by the UE on the first antenna port and the second antenna port, or is obtained by the UE according to the measurement result of any one of the first antenna port and the second antenna port and the power deviation value. If the offset value of the first antenna port relative to the second antenna port is +3 dB, the RSRP value of the second antenna port is obtained by subtracting 3 dB of the measured RSRP value on the first antenna port. Specifically, for the first antenna port and the second antenna port, the average gain quasi-co-station, and the first antenna port and the second antenna port are adjusted according to the power deviation value, the average gain is a quasi-co-station, and the UE may The first antenna port measures an RSRP value, measures an RSRP value according to the second antenna port, and then statistically averages or weights the two RSRP values to obtain a final RSRP value, and reports the obtained final RSRP value. Alternatively, the UE may jointly measure an RSRP value according to the first antenna port and the second antenna port, and report the measured RSRP value.

When the first antenna port and the second antenna port are adjusted according to the power offset value, and the average gain is the quasi-co-station, the UE measures an RSRP value according to the first antenna port, and receives according to the average configuration. The power deviation value is adjusted. If the deviation value of the first antenna port relative to the second antenna port is +3 dB, then the measured RSRP value is subtracted by 3 dB to obtain an RSRP value, and another RSRP value is measured according to the second antenna port, and then A statistical average or weighted average of the two RSRP values is used to obtain a final RSRP value, and the resulting final RSRP value is reported.
